In mammals, a robust physiologic system acts to maintain relative constancy of weight. A key element of this system is leptin. The nature of this "brain-somatic" cross talk is as yet poorly understood, but it is likely to have important implications for the pathophysiology and treatment of obesity, diabetes and other metabolic disorders.

In the past five years, so much additional progress has been made in ourunderstanding of both the basic and c1inical aspects of a wide variety of thyroid disorders that a second edition of Diseases of the Thyroid was considered a necessary addition to the Contem- porary Endocrinology series. Fresh perspectives also seemed warranted, so we recruited new authors for many of the chapters and believe that this edition will provide the reader with further insights into the pathophysiology and c1inical presentation and treatment of thyroid disease. It inc1udes topics ranging from neonatal thyroid screening, thyroid dysfunction during infancy and childhood, peripartum thyroid disorders, thyroid disease in the elderly, and the c1inical relevance of the sodiurnliodide symporter (NIS) to the pathogenesis and treatment of nodular goiter, thyroid cancer, thyrotoxicosis, and hypothyroidism. The worldwide problem of iodine deficiency and its eradication is also discussed, along with environmental goitrogens and iodine-induced thyroid disease. I am indebted to all the contributors for their cooperation and expertise in providing their chapters in an extremely timely fashion, to Mr. Thomas Moore and Mr. Craig Adams from Humana Press for their expert assistance, and to Ms. Christine Archung for providing superb administrative assistance.

As a draining and secretory system, the nasolacrimal ducts play a role in tear transport and non-specific immune defense. In this book recent advances about the nasolacrimal ducts have been summarized and discussed in context with nasolacrimal duct pathophysiology.

Long recognised as the standard two volume reference work on the scientific basis and clinical practice of radiology, the new edition of 'Textbook of Radiology and Imaging" has been thoroughly revised and up-dated in order to incorporate the latest technologies and modalities in the field. This book provides the radiologist in training and in practice with a concise, clearly written overview of the applications of the full spectrum of imaging modalities used in daily clinical practice. The book is organised by body system and incorporates an integrated, multi-modality approach to radiological diagnosis. Throughout, the emphasis is on the clinical effectiveness of contemporary imaging practice and the text is supported with abundant high-quality illustrations.

Regional anaesthesia, particularly central neural block for obstetrics, has increased greatly in use and popularity over the last 30 years. However, a significant number of anaesthetists still find it difficult to acquire either a theoretical grounding in the subject or expertise in the techniques. This book is produced to help them to rectify this situation. It is aimed at anaesthetists in training and those studying for the FRCA examination, as well as senior anaesthetists whose training was completed before the revival of interest in regional anaesthesia. Those already using regional techniques will find the book useful for extending and updating their knowledge. As in the first two editions, the first part of the book gives an account (firmly based in recent research) of the theoretical aspects of regional anaesthesia. The second part describes the practical applications of the various methods. The third edition continues to give a clear view on often misunderstood subjects such as the pharmacokinetics and systemic toxicity of local anaesthetic drugs, and the use of test doses as well as an assessment of the present place of spinal anaesthesia and an account of the features of some of the newer spinal agents. The contributing authors use the techniques which they describe in their daily practice and, because they come from a variety of backgrounds, the book is broadly representative of British practice. However, the editors have ensured that the guidance given and the opinions expressed are clear and unequivocal.

The infratemporal fossa is one of the most important anatomical regions in the head for dental and maxillofacial surgeons as it contains the teeth's major nerves and vessels; is the site of the temporomandibular joint and associated muscles that move the jaw; is a site often involved in facial fractures; is the route to the lateral skull base and middle cranial fossa; and can be the site of benign and malignant tumors. Surgical Anatomy of the Infratemporal Fossa integrates the basic clinical and surgical anatomy of the regions. It contains comprehensive clinical coverage of the infratemporal fossa with chapters relating to anatomy, local anesthesia, spread of infection, trauma, tumors, surgical access and pain. The contributors are internationally recognized experts in their fields and the detailed text is accompanied by high quality illustrations (the majority in color). Dentistry specialists, head and neck surgeons and trainees in those fields will find this text indispensable.

Continuing in the tradition of the popular 'Secrets' Q&A format, this thoroughly revised and expanded edition includes new chapters on Laparoscopic Surgery for Genitourinary Tumors and well as Cystocele and Rectocele.

Core Cases in Critical Care describes the clinical management of some of the most common problems seen in the critically ill patient. Twenty detailed, illustrative case histories are presented and for each, descriptions of the problem, its underlying pathophysiology and the key principles of principles of patient management are given. Each 'case' is written by experts in the field, and all contributors are practising anaesthetists and critical care specialists of many years' experience. Core Case in Critical Care is essential reading for all trainees in critical care, and will also prove a valuable addition to the libraries of other groups such as critical care nurses, surgical trainees and practising critical care physicians and anaesthetists, both as a useful summary of key topics in critical care in an easily-digested format, and as a stimulus for discussion and analysis of current practice.
